Current conditions: indoor humidity: 35%. Outdoor: 51 degrees. Do point: 26. I installed a separate transformer for humidifier and wired to enable humidifier operation in fan only mode. I set blower speeds. Stage one: 1156 CFM, delay: 180Sec. Fan mode: 1250 CFM. Suggestions: set thermostat fan switch to “on“ for continuous humidifier operation when needed. Monitor indoor humidity with accurate hygrometer.
